3 Claims. (01. 131-198) This invention relates to certain new and usefulimprovements in smokers pipes.

The primary object of the invention is to provide a smokers pipe whereinthe smoke passage from the bowl of the pipe to the tip of the mouthpieceis extended in a sinuous line to increase the length of smoke travelbefore entering the mouth of the smoker, and being operative for coolingthe smoke duringsaid sinuous passage.

A further object of the invention is to provide a smokers pipe of theforegoing character wherein the bowl of the pipe is formed with anenlargement that is vertically chambered and constructed to providesinuous smoke passages for increasing the length of smoke travel fromthe bowl of the pipe to the tip of the mouthpiece so as to cool thesmoke during use of the pipe.

A still further object of the invention is to provide a smokers pipewherein the bowl ofthe pipe is provided With a lateral enlargementhaving a chambered portion for the reception of a metallic cylinder intowhich a removable metallic plug with tortuous passages therein ismounted, the upper end of the plug being constructed for the admissionof air thereinto for mixture with the smoke flowing from the pipe bowlto the mouthpiece for the purpose of cooling the smoke and reducingcondensation to a minimum, the heat of the smoke being furtherdissipated by conduction to the atmosphere during its flow in contactwith the metallic cylinder and plug.

It is a further object of the invention to provide a smokers pipewherein the bowl portion is provided with a lateral enlargement that isvertically bored to communicate with the smoke passage through the stemof the pipe with a chamber at the upper end of the enlargementcommunicating with said bored portions and closed at its upper end by avented metallic cap to cause the smoke flowing from the bowl to travelin a sinuous path to the mouthpiece of the pipe for cooling of th smokeand condensation of moisture therein.

With the above and other objects that will appear as the nature of theinvention is better understood, the same consists of the novelcombination and arrangement of parts as Will be more fully pointed outin the following description.

In the drawing:

Figure 1 is a top plan view of a smokers pipe constructed in accordancewith the present invention;

Figure 2 is a vertical longitudinal sectional view taken on line 2--2 ofFigure 1, showing the lateral enlargement carried by the bowl of thepipe with the sinuous smoke passage therethrough;

Figure 3 is a side elevational view of the metallic plug removed fromthe lateral enlargement of the pipe bowl, and

Figure 4 isa vertical longitudinal sectional view of a pipe bowl andstem in which the tortuous passages for the smoke are directly formed inthe lateral enlargement of the pipe bowl.

7 Referring more in detail to the accompanying drawing and particularlyto Figures 1 to 3, there is illustrated a smokers pipe formed of anysuitable material such as briar or the like that comprises a tobaccobowl 5 carrying a laterally "directed stem 6 to which the usualmouthpiece! is removably attached. The base of the bowl 5 has a smokepart 8 therein communicatin therewith and a smoke passage 9 extendingthrough the stem 6 to the mouthpiece 1. 'Asshown more clearly in Figure2, the pipe bowl 5 and stem 6 has an enlargement l0 formed integraltherewith, which rises from the stem 6 and is disposed laterally of thebowl 5 and at the side thereof nearest the mouthpiece l. The enlargementI0 is provided with a vertical opening H which extends through the upperend of the enlargement and terminates at its lower end as at l2 belowthe smoke passage 9 in the stem 6, and formsaseat.

A metallic cylinder l3 having a closed'bottom l4 and open upper end isfrictionally received within the vertical opening H with the bottom walll4 thereof resting on the seat l2, while the upper end of the cylinderl'3 is flush with the upper end of the enlargement H]. A cylindricalmetal1ic plug I5 is fractionally received in the cylinder l3, and isremovable from the cylinder for cleaning purposes. The plug is supportedat its lower end on the bottom wall M of said cylinder, and is centrallycut away at its upper end to provide a chamber l 6, while the lowerportion of said plug is bored to provide a pair of vertically extendinglongitudinally spaced smoke passages l I and I8 communicating at theirupper ends with the chamber Hi. The passages l1 and I8 are provided attheir lower ends with laterally directed ports l9 and 20 which registerwith openings 2| and 2|" in the side wall of the cylinder l3 and arealined with the smoke passage 9 in the stem 6 of the pipe.

A metallic plug or cap 2| provided with a central vent 22 is removablythreaded into the upper end of the cylinder l3 as shown in Figure 2.

From the above detailed description of the invention it is believed thatthe construction and use thereof will at once be apparent, it beingnoted that smoke from the bowl 5 entering the port 8 travels through theextended sinuous passages l'! and I8 in the plug 15 before entering theoutlet end of the smoke passage 9 in the stem 6 to the mouthpiece 1. Alimited quantity of air enters the chamber l6 at and through the capvent 22, for admixture with the smoke to aid in cooling the smoke and beeffective for reducing condensation to a minimum. Also, the cylinder l3,plug 15 and plug closure 2| being formed of metal, a large amount ofheat in the smoke is reduced by conduction to atmosphere and therebyproduces a cool and pleasant use of the pipe. The plug I5 whilefrictionally retained within the cylinder may be readily removed forpurposes of cleaning and the like.

In the form of the invention illustrated in Fig ure 4, the pipe bowl 5acarries a lateral stem 6a with a smoke passage 9a therein while anenlargement Illa rises from the stem 6a and is carried laterally of thebowl 5a. The upper end of the enlargement Illa is vertically chamberedas at 16a and below said chamber there is a pair of longitudinallyspaced vertical passages Ila and l8a that extends below the smokepassage 9a. in the stem. A removable metallic cap 2 la is provided andhas a center vent 22a, the cap closing the upper end of the chamber 16a.The smoke from the bowl 5a enters the passage 9a through the port So atthe lower end of the bowl, travels upwardly through the passage l'ia,enters the chamber Mia and then passes downwardly through the passage18a to the smoke passage 9a.

While there are herein shown and described the preferred embodiments ofthe invention, it is to be understood that minor changes may be madetherein as will fall within the scope of the invention as claimed.

I claim:

1. In a tobacco pipe of the character described, a bowl having a stemprojecting therefrom and having a smoke conducting passage leading fromthe bowl through said stem, an enlargement on the bowl disposedlaterally thereof and rising from the stem, said enlargement beingprovided with a vertical chamber communicating with the smoke conductingpassage and having an opening at its upper end and with the bottom wallthereof disposed below said smoke conducting passage, a metalliccylinder seated in said chamber and resting on the bottom wall of thelatter and communicating with the smoke conducting passage, and a plugremovably mounted in said cylinder having tortuous passages thereincommunicating with said smoke conducting passage to cause the smoke fromthe pipe bowl to travel in a sinuous path in its passage from said bowlto the outlet end of the stem.
